LONG-TERM EFFECTS ON RENAL-FUNCTION OF SU CCESSFUL PERCUTANEOUS TRANSLUMINAL RENAL ANGIOPLASTY IN 140 HYPERTENSIVE PATIENTS

Long term effects on creatinine serum level of successful percutaneous transluminal renal angioplasty were retrospectively studied in 140 pa tients. 3 groups were distinguished: the first one (80 patients) inclu ded unilateral renal angioplasties, with normal controlateral kidney a nd renal artery; the second group (35 patients) included bilateral ren al angioplasties; the third group (25 patients) included solitary kidn ey renal artery angioplasties. In each group, subgroups were defined w ether creatinine serum level was upper or lower than 130 mu mol/l. Ren al fonction was considered to be improved if serum creatinine was redu ced by 20% or more, maintained if serum creatinine variations were bel ow 20%, worsened if its increasement was upper than 20%.
